UNITED s T TEs PATENT QFFICE- HERBERT A. BERKMAN, OF CHICAGO, ILLINOIS, ASSIGNOR TO ZIM MANUFACTURING COMPANY, A C()RPORATION OF ILLINOIS:

ACTUATING HANDLE FOR A RECIPROCATING MEMBER.

I Application filed June 10, 1925. Serial No. 36,213.

To all 'a' hom it 772 (1,2 concern Be it. known that I, HERBERT 'A. BERK- MAN, a citizen of theUnited States, .resid ing in Chicago, county of Cook, State of Illinois, have invented a certain new and useful Improvement in Actuating Handles for a Reciprocating Member, and declare the following to be a full, clear, and exact description of thesame, such as will enable others skilled in the art to which it pertains to make and use the same, reference being had to the accompanying drawing, which forms a part of this specification.

There are various devices on automobiles and elsewhere that are ac uated by a pull handle connected to a wire. The object of the present invention is to produce a sim ple and novel construction and arrangement for attaching such av handle to a wire and permitting the handle to be readily looked in any desired position, by a turning movement, without twisting the wire.

A further object 'of the present invention is to produce a simple and novel mounting on the dash of an automobile for a pull handle device. I V

The various features of novelty whereby my invention is characterized will hereinafter be pointed out with particularity in the claims; but, for a full understanding of my invention and of its objects and advantages, reference may be had to the following detailed description taken in connection with the accompanying drawing, wherein:

Figure 1 is a central vertical longitudinal section through one of my improved devices adap ed to be mounted on an automobile dash, the parts being shown in an unlocked condition; Fig. 2 is a view similar to Fig. 1, showing the parts in a locked condition; Fig. 3 is a section taken on line 33 of Fig. 2 and Fig. 4 is an elevation of the expanding nut looking at one of the corners of the latter.

Referring to the drawing, 1 represents a sleeve-like part the opening in which is round at one end, as indicated at 2, between an annular enlargement or groove 3 and said end, while the remainder of the bore is noncircular, preferably square as indicated at 4. Adjacent to the end having the round bore portion are two upwardly projecting lugs 5 and 6 spaced apart from each other. Through one of the lugs extends a set screw 7 that is adapted to cooperate with theother end of the wire is passed through an open-- ing 11 in a projection 12 on one end of a cup-shaped nut 13 having a cross section corresponding to that of the non-circular portion ofthe bore, and slightly smaller than the latter so that the nut may be moved along the bore. The nut is split, conveniently at the corners from the open end toward the base, as indicated at 14, and it is made ofa more or less resilient material which permits ,it'to expand and then to resume its normal shape when the expanding pressure is removed,. Extending into the opposite end of the member 1 from that through which the wire enters is a stem 15, preferably circular in cross section, having at its outer end a handle 16. The inner end of the stem is reduced in diameter and is screw-threaded, as indicated at 17, to fit the nut, At the base of the screw-threaded portion of the stem is a frusto-conical section 18, that joins the screw-threaded section to the body of the stem; this frustoconical part constituting a wedge adapted to enter the mouth of the cup-shaped nut and expand the sides of the nut laterally.

As long as no portion of the wedge enters the nut, the latter remains smaller in cross sectional area at all points than the interior of the square bore, so that the stem may be reciprocated to move the wire lengthwise. When it is desired to 1001; the wire in any position to which it has been brought, the

In other words, the nut need not be locked so tightly as to necessitate the turning of the handle before the nut can be moved, but the nut may be held against thesurrounding walls with-any desired degree of pressure, so that the handle may be moved backiand forth but will :be frictionally held against accidental displacement.

By making the major portion of the bore in the supportingztube non-circular ineross section, the screwing and unscrewing of the stem cannot cause any turningmoyement of the nut and, therefore, cannot produce any twist in the Wire:

ltwill thus beseeir th'at Ihare produceda simple and novel construction which per-=- mits an operating handle to-be =1'eadilygat cachedtothe lower" edge o-t a dash, permits awire and the actuating member th'eretor tohe readily connected to and disconnected froin-'eaolr o-ther; insures-that the wii-e'willnOt b e twistedin use or during the process of: fastening it-ito'or untastenin g it fromthehandle; and enables the user firmly to lock the handleand its'connected Wire in anypo sition of adjustment or else to h'ol-d it" the tio-nally with any desired "degree of pressure in any such position:

While I have illustrated and described with particularity only a" siirgle l preferred form of my' invention; Ido -not desire-tcl be limitedto the exact structural details tl' illustrated and described; but intendto" cover all i orms andl arrangements which- COHTG. within the definitions of my invention constituting the a-p pended 'cl'ain'1s.-
